The Passthrough camera is....strange. It's appears to be a stitched together feed and you can tell it quite clearly. Very grainy and distorted.

I ended up selling my CV1 once my link cable came, I think you'll be pleased once it arrives.
Something that helps with Quest comfort is to make a roll of coins weighing about 300g and attach it to the back of the strap, this balances the front heavy weight of the headset and means its not leaning on your cheek bones. Weirdly it makes it feel as though it weighs a lot less.
